TABLE 



OF THE PROBABILITIES OF THE DURATION OF L1FK. 



By this Table, it appears that we may lay our belt 

 one to one, that an infant newly born will live eight 

 years ; that an infant of one year will live thirty-three 

 years longer ; that an infant of two years will live 

 thirty-eight years longer ; that a man of twenty will 

 live thirty-three years and five months longer ; that a 

 man of thirty will live twenty-eight years longer; and 

 so proportionally of every other age.
